The role of antithrombotic therapy is well known for its primary and secondary prevention of cardiovascular disease by decreasing the incidence of acute cerebral, cardiovascular, peripheral vascular, and other thrombotic events. The overwhelming data show that the risk of thrombotic events is significantly higher than that of bleeding during surgery after antiplatelet drug discontinuation. It has been assumed that discontinuing antiplatelet therapy prior to performing interventional pain management techniques is a common practice, even though doing so may potentially increase the risk of acute cerebral and cardiovascular events. There are no data available concerning these events, specifically in relation to the occurrence of thromboembolic events, even though some data are available concerning bleeding complications. Even then, interventionalists seem to routinely discontinue all antithrombotic therapy prior to all interventional pain management techniques. ⋯ The results illustrate an overwhelming pattern of discontinuing antiplatelet and warfarin therapy as well as aspirin and other NSAIDs prior to performing interventional pain management techniques. However, thromboembolism complications may be 3 times more prevalent than epidural hematomas (162 versus 55 events). It is concluded that clinicians must balance the risks of thromboembolism and bleeding in each patient prior to the routine discontinuation of antiplatelet therapy.

Randomized Controlled Trial
The effect of Helicobacter pylori eradication on migraine: a randomized, double blind, controlled trial.
Recent studies have shown a positive correlation between Helicobacter pylori (H. pylori)infection and migraine headache. ⋯ H. pylori eradication may have a beneficial role on migraine headache. This shows the significance of H. pylori treatment in the management of migraine headache among Iranian patients.

Lumbar facet joints are a well recognized source of low back pain and referred pain in the lower extremity in patients with chronic low back pain. Conventional clinical features and other non-invasive diagnostic modalities are unreliable in diagnosing lumbar zygapophysial joint pain. Controlled diagnostic studies with at least 80% pain relief as the criterion standard have shown the prevalence of lumbar facet joint pain to be 16% to 41% of patients with chronic low back pain without disc displacement or radiculitis, with a false-positive rate of 17% to 49% with a single diagnostic block. ⋯ There is good evidence for diagnostic facet joint nerve blocks with 75% to 100% pain relief as the criterion standard with dual blocks, with fair evidence with 50% to 74% pain relief.

Therapy with glucocorticoids often results in bone loss and glucocorticoid-induced osteoporosis. However, the relationship between epidural steroid injection (ESI), bone mineral density (BMD), and vertebral fracture remains to be determined. ⋯ Older age and lower BMD were associated with osteoporotic fracture in postmenopausal women treated for low back pain with ESI. The ESIs were not associated with low BMD or fracture.

Clinical Trial
Study of percutaneous lumbar decompression and treatment algorithm for patients suffering from neurogenic claudication.
Symptomatic lumbar spinal stenosis (LSS) patients often suffer from multiple etiologies, and patient symptoms must be differentiated and identified as either neurogenic claudication, radicular pain, or both. The most common symptom associated with LSS is neurogenic claudication, which has been reported to occur in 91% to 100% of the LSS patient population. Neurogenic claudication symptoms are described as pain radiating to the lower extremities that begins and worsens as the patient ambulates. Neurogenic claudication symptoms worsen over time and can eventually result in significant life-altering functional limitations. Symptomatic LSS patients may also suffer from radicular pain, which is a persistent pain transmitted through neural pathways, and is associated with inflammation of the exiting nerve root. ⋯ In this study, the mild procedure was shown to be safe. In addition, patients experienced significant improvement in mobility and reduction of pain one year after the procedure. One-year outcomes were not significantly different from interim results, indicating that the significant improvement following treatment, occurring as early as 12 weeks, was maintained through one year. This high degree of consistency over time indicates the durability of percutaneous lumbar decompression in the treatment of neurogenic claudication in symptomatic LSS.
